Smush Parker, a former Los Angeles Lakers point guard who was the Heat's biggest free agent acquisition, enters his fourth game of the season still uncertain of his role with Miami.

He has not played in the past two games. And, he is not guaranteed to be in the rotation Wednesday night when the Heat (0-3) visits the defending champion Spurs.

Heat coach Pat Riley said Tuesday that Parker still has yet to factor into the mix at point guard and is better suited as a reserve shooting guard -- where minutes also are tough to come by behind Ricky Davis and rookie Daequan Cook.

"No, he hasn't [shown enough]," Riley said when asked why Parker has remained on the bench the past two games. "That's the reason. He'll get his chance. He's more of a scoring point [guard]. I really don't need that right now. What I want is somebody who'll get us organized."
